@ExergyDev Let’s assume that’s true, after 1000 flights how much weight is that?
English
@idlehandsdev At best this offers a 5% increase in cargo capacity to orbit depending on the exact orbital parameters.
English
I know everyone is jumping on this bandwagon, but honestly does anyone have a legitimate reason why the falcon 9 has landing legs at all? I’ve wondered this forever. If they have designated landing locations anyway, and can’t deviate landing site, why waste fuel flying them?

How the cable was closing up & catching of the CZ-10B 1st stage.

@MarkBHyde How will spacex get 5000 tons of concrete and rebar to the moon??

I want everything in my house to be made by 3M

One of the easiest ways to healthmaxx is to get the 3M high fluoride toothpaste. Also 3M toothpaste is a vibe in general.

@stkaweesi I’m thinking the “it looks cool” had a major weigh in on the decision too
English
@idlehandsdev I think someone thought, " a rocket with legs looks pretty cool...let's do that"
And probably also because the very idea of catching a rocket sounded absurd till like 4 years ago
English
@GrandProtector I think you’re underestimating how challenging and expensive they were to develop. Not just a “rocket with legs”, but a specialized lightweight mechanism and structure integrated into the rocket body and took a lot of clever engineering, money, and destroyed boosters to get right
English
@idlehandsdev While it saves dry mass and fuel to offload landing equipment to the landing site, it also tends to make the actual landing itself much more complicated.
A rocket with legs only needs a wide flat area.
A catcher needs a far higher amount of landing precision.
English
@MikeM_UK_ I agree but I also think someone maybe thought it would look cooler to land on their own legs. lol
English
@idlehandsdev You kinda have to build a big tower. Leg simpler. Spacex started this and made movable with drone ships so wait for the next development catching the second stage. Next flight next week.
English
@MannyCalavera13 Legs = Weight, every bit of extra weight on the ship is some percentage of weight that can’t be payload, less payload to space means more flights. More flights is more fuel.
English
@BigFire97827414 Okay so falcon 9 can keep flying those, and falcon 9.5 can fly without 😂
English
@idlehandsdev SpaceX is not allowed to do any major changes to Falcon 9 after being locked into manned flights. Hence Starship program
English
@StevenMackey Counterpoint, you don’t need to manufacture and carry heavy landing legs for 600+ flights if you build a couple metal cages. Why do they need to land anywhere? They have never deviated from a landing site without requiring a RUD or splashdown. It would be cool if they did though
English
@idlehandsdev You don’t need a giant heavy metal cage to be super mobile in the middle of the ocean if your rocket has legs.
A rocket with legs can land virtually anywhere.
English
@DeanLogic The falcon 9 booster is incapable of reaching either of those, and even if it could the legs would still need a landing pad built.
English
@idlehandsdev "why the falcon 9 has landing legs at all"
Because there isn't a catching station already built in the Moon and Mars.
English
@idlehandsdev Cause no one thought of it until the first version of starship. Really. No one in the entire world thought it was feasible to catch a rocket.
English
Most machinist just get the part made.

Most machinists spot drill all wrong. Even worse, some still use a center drill to do their spot (gaww!). You need to use a spot drill with LARGER angle, to ensure the drill center contacts first and also doesn't crash the flute edges too.

I’ve been looking for a solution for storing these forever!

Dust(or something small like a bug) being illuminated by the IR lights, too close for the aspherical lens to focus on, giving the wide oval shape. The spinning look is likely something to do with the IR lighting PWMing as a frequency out of phase of the cameras shutter.

So....the Ring camera we use to see if the dog wants to come in captured this at 3:30 am a couple of nights ago

.@idlehandsdev built a GPS-powered watch for @geerlingguy that doesn't tell time — it just proves two clocks are perfectly synced. hackster.io/news/the-watch…

@idlehandsdev @geerlingguy This video introduced me to @idlehandsdev ‘s videos. Holy crap, top notch, and insta sub.

Friend and fellow time enthusiast @geerlingguy stopped by the bunker the other day and I got him to build his first bare circuit board. Everything mostly went to plan…
